How the National Science Foundation helped cement the use of American Sign Language

There are more than 300 separate sign languages worldwide

Each of these languages has its own grammar, vocabulary and cultural associations. American Sign Language, the predominant Deaf language in the US, is part of the broader French Sign Language family, which means it shares historical influences and similarities with French Sign Language (which is called LSF). International Sign is a simplified, makeshift form of communication that borrows from many languages, and it's used at international deaf conferences, among other locations.

How the NSF Public Understanding of Science program fueled science interest and literacy

To support STEM education at all levels and in all settings, the NSF has invested in public-facing science projects since 1957. These investments produced science education storytelling and entertainment programming, including "Bill Nye the Science Guy," "The Magic School Bus," and the "Flight of the Butterflies" and "Blue Whales" IMAX films.

The history of the National Science Foundation Network, a precursor of the internet

Although ARPANET connected various national laboratories and supercomputing facilities by the 1970s to facilitate scientific collaboration, the system was slow and required highly trained operators. The launch of NSFNET in 1986 provided a more flexible and powerful network that went on to connect over 170 academic and research communities and link to its European counterpart, EASInet.

Audism is institutionalized discrimination against deaf people

Promoting the idea of hearing-at-all-costs in medical and education settings has created division in the deaf community and influenced decisions about learning sign language.

The origin of the term STEM—science, technology, engineering, and mathematics—at the NSF

In 2001, Judith Ramaley coined the acronym while director of the National Science Foundation to replace "SMET," which was considered awkward-sounding. Since then, additional elements have been incorporated in various settings to modify the acronym, such as STEAM-based education, which includes art.

View the evolution of the National Science Foundation logo

When the agency was established in 1950, the logo featured an eagle holding a shield with symbols of a pyramid, a test tube, a microscope, and a lamp from which light radiated. Subsequent logos featured variations of a ring composed of people holding hands, which would eventually be redesigned to enclose a globe bearing the "NSF" abbreviation.

Noam Chomsky believed it might be possible to communicate with aliens

The father of modern linguistics argued that there is a genetic component to language, and that the ability to acquire and comprehend language is innate. If aliens existed, he believed they could potentially observe the same "universal grammar" rules as humans.

Eleven deaf men played a pivotal role in America's human spaceflight program

In the mid-20th century, 11 deaf men volunteered for a series of experiments that offered unprecedented insights into the effects of weightlessness on the human body. Most of the men had become deaf in early childhood as a result of spinal meningitis, a condition known to damage the vestibular system and make them less susceptible to motion sickness. For a decade, these men participated in extreme motion sickness situations, including living in a slowly spinning room, spending time in centrifuge pods designed to simulate hypergravity, and flying in parabolic flights sometimes referred to as the "Vomit Comet." (Some users may experience a paywall.)

Watch how Sanger sequencing kickstarted the first generation of DNA sequencing

The first compiler to facilitate communication with computers was developed by Grace Hopper

The A-0 program linker automatically translated mathematical symbols into machine-readable binary code. Although it took two years for computer executives to get on board with the idea, the technology was foundational to future programming languages that allowed computers to understand commands written in word-based languages.

Once whale songs were discovered, conservation efforts boomed

Until the 1950s, humans believed whales were mute. Once American underwater surveillance systems caught their sounds during the Cold War, the perception of the creatures changed, leading humans to campaign for whaling bans and long-term conservation efforts. These captivating whale songs can be heard throughout the ocean.

The GI Bill helped expand formal jazz education

Berklee School of Music (then known as the Schillinger House) and a program at the University of North Texas (then known as Texas State University) established academia's earliest jazz programs in 1945. The GI Bill provided World War II veterans with educational funding, which helped the programs proliferate: By the end of the 1960s, there were 450 college jazz ensembles.

Using AI to restore speech 30 years after a stroke

The origin of LASIK eye surgery, from a lab incident to federal funding and widespread use

After a University of Michigan engineering student suffered retinal burns from an ultrashort pulse laser, researchers realized it could be used to reshape the cornea and improve a person's vision with greater precision than a scalpel and earlier laser technologies. Agencies, including the National Science Foundation, the National Institutes of Health, and the Department of Energy, provided funding to develop and commercialize the procedure.

Linguists proved Shakespeare wrote his plays

In the 1800s, linguist Wincenty Lutoslawski invented a method of linguistics analysis called stylometry to help certify literary authorship. Stylometrists concluded that Shakespeare wrote his plays, and likely collaborated with Christopher Marlowe for some.

19th-century Americans used technology to try to prove the existence of ghosts

In the 19th century, following technological advancements like the telegraph, phonograph, and others, efforts were made to capture proof of ghosts. These technologies seemed supernatural in their own right and emerged at the same time Spiritualism took off in the US, resulting in new approaches to connecting with the dead.

Autism Spectrum Disorder, defined in 2013, was previously categorized as numerous disorders

This exploration of ASD history walks through how autism science and diagnoses have evolved over the decades, including the new category in the DSM-4 in 1994 that created Asperger's disorder and pervasive developmental disorders, and the new, broader ASD definition in 2013 in the DSM-5 that has led to more diagnoses.

Title IX was signed into law in 1972
